3D Printing Australia: Custom Components for Industrial Fermentation and Bioprocessing Equipment

Because every facility may have different vessels, instruments, production requirements, and equipment layouts, standard components are not always sufficient. Engineering teams may require custom brackets, sensor holders, laboratory fixtures, prototype manifolds, equipment covers, positioning tools, and specialised accessories.

3D printing Australia provides a flexible approach for developing these low-volume and customised components, particularly during equipment prototyping and process development.

Forge Labs can support businesses and engineering teams with additive manufacturing for prototypes, customised components, fixtures, and selected low-volume production applications.

The Role of 3D Printing in Bioprocessing

Bioprocessing equipment can contain many small components that support the main processing system.

Examples include:

• Sensor mounts
• Sampling fixtures
• Tube guides
• Instrument brackets
• Equipment covers
• Positioning fixtures
• Prototype manifolds
• Cable-management parts
• Laboratory accessories

These components often have unique dimensional requirements.

3D printing allows engineers to create geometries specifically around the equipment being developed.

Custom Bioreactor Accessories

Bioreactors require careful control of operating conditions and instrumentation.

During equipment development, engineers may need customised accessories for:

• Sensor positioning
• Probe mounting
• Tubing management
• Sampling arrangements
• Instrument support
• Equipment integration

Printed prototypes can be modified quickly when the configuration changes.

Sensor Mounting Fixtures

Fermentation systems can use sensors to monitor variables such as temperature, pH, dissolved oxygen, pressure, and other process conditions.

A sensor may need to be mounted at a specific position relative to the vessel or process equipment.

3D printed holders can be designed around the dimensions of individual instruments.

Potential applications include:

• Probe brackets
• Sensor holders
• Cable supports
• External instrument mounts
• Prototype positioning systems

The material must be appropriate for the environment and intended use.

Sampling-System Prototypes

Sampling systems allow operators and researchers to obtain material from a process for analysis.

Different processes can require different sampling arrangements.

3D printing can support prototypes for:

• Sample holders
• Tube-routing fixtures
• Valve positioning aids
• Instrument mounts
• Laboratory handling accessories

For sterile or direct-process-contact applications, material selection, surface characteristics, cleaning, sterilisation, and applicable validation requirements must be carefully assessed.

Tubing and Hose Management

Bioprocessing equipment can contain numerous tubes and hoses.

Poor routing can make equipment difficult to operate and maintain.

Printed clips and guides can help organise tubing around suitable non-critical areas.

Applications may include:

• Tube clips
• Routing guides
• Hose supports
• Identification holders
• Instrument-cable management

These parts can be customised to fit the specific equipment layout.

Laboratory Fermentation Equipment

Research laboratories frequently use small-scale fermentation systems.

Because laboratory equipment is often modified for individual experiments, standard accessories may not always provide the required fit.

3D printing can produce:

• Vessel holders
• Sample racks
• Sensor mounts
• Tube organisers
• Instrument brackets
• Experimental fixtures

Researchers can modify the digital design as experimental requirements change.

Prototype Manifolds

Fluid and gas distribution systems may require customised manifolds.

During early development, engineers may want to evaluate different port arrangements before manufacturing the final component.

3D printing can support prototype development of manifold geometries for appropriate low-risk testing environments.

Engineers should carefully evaluate pressure, temperature, fluid compatibility, permeability, and cleaning requirements before using printed manifolds in operational systems.

Fermentation Vessel Accessories

Large and small fermentation vessels may require supporting components around their primary structure.

Printed accessories can include:

• External sensor brackets
• Equipment labels
• Cable guides
• Instrument supports
• Positioning fixtures
• Prototype access components

These can be designed around the vessel's specific dimensions.

Automated Bioprocessing Systems

Modern bioprocessing increasingly incorporates automation.

Automated systems may control:

• Fluid movement
• Sampling
• Temperature
• Mixing
• Sensor readings
• Dosing
• Filtration

Automation equipment often requires customised mechanical interfaces.

3D printing can support the development of:

• Robotic grippers
• Instrument brackets
• Tube-routing systems
• Sensor mounts
• Component holders
• End-of-arm tooling

Robotic Sample Handling

Laboratories may use robots to move sample containers between instruments.

Each container type can require specific handling geometry.

Printed gripper prototypes can be designed around:

• Container shape
• Diameter
• Height
• Weight
• Label position
• Handling orientation

Rapid prototyping makes it easier to test different gripping concepts.

Machine Vision for Bioprocess Equipment

Machine vision can support laboratory automation and equipment inspection.

Cameras may need precise positioning relative to samples, containers, or instruments.

3D printed mounts can be customised for:

• Cameras
• Lenses
• Lighting
• Sensors
• Inspection fixtures

This can support the development of automated inspection systems.

Custom Sample Racks

Laboratories frequently need racks for containers with specific dimensions.

Commercial racks may not always match unusual sample sizes.

3D printing can create customised racks with:

• Specific hole diameters
• Custom spacing
• Defined container orientation
• Integrated labels
• Modular sections

For laboratory environments, material compatibility and cleaning requirements should be evaluated.

Prototype Filtration Equipment

Filtration is used in many bioprocessing applications.

Engineering teams may need to develop custom interfaces between filters, tubing, sensors, and other equipment.

3D printing can support prototypes for:

• Filter holders
• Alignment fixtures
• Instrument brackets
• Tubing guides
• Test fixtures

Final filtration components require appropriate engineering and material validation.

Equipment Integration

New instruments often need to be integrated into existing equipment.

The challenge may involve limited space or unusual mounting geometry.

A printed bracket can be designed around:

• Existing mounting holes
• Instrument dimensions
• Cable clearance
• Tubing routes
• Access requirements

This can simplify prototype integration before final fabrication.

Maintenance Fixtures

Bioprocessing equipment requires regular maintenance and inspection.

Technicians may need specialised fixtures for specific machines.

3D printing can provide suitable low-load tools and accessories such as:

• Alignment fixtures
• Component holders
• Protective covers
• Installation guides
• Tool organisers

The design should reflect the actual mechanical forces involved.

Replacement Accessories for Older Equipment

Laboratory and industrial equipment can remain operational for many years.

Small plastic accessories may become difficult to source even though the primary machine remains functional.

Potential replacement applications include:

• Clips
• Covers
• Knobs
• Sensor holders
• Cable guides
• Racks
• Brackets

Reverse engineering can help recreate suitable components where original documentation is unavailable.

Reverse Engineering Bioprocess Components

An existing part can sometimes be used as the basis for a digital reconstruction.

The process may involve:

1. Measuring the original component.
2. Creating a CAD model.
3. Identifying important dimensions.
4. Selecting a suitable material.
5. Producing a prototype.
6. Checking fit.
7. Revising the design.
8. Producing the approved component.

This can be useful for specialised laboratory equipment and legacy systems.

Prototyping Fluid-Handling Systems

Fluid movement is central to many bioprocessing applications.

Engineers may need to test different arrangements of:

• Tubing
• Valves
• Pumps
• Sensors
• Containers
• Filters

3D printed fixtures can help establish physical layouts before final equipment is produced.

Low-Volume Manufacturing

Bioprocessing equipment frequently involves specialised components rather than mass-produced parts.

A manufacturer may require only a handful of components for a particular system.

3D printing can be suitable for:

• Engineering prototypes
• Custom fixtures
• Experimental tooling
• Equipment accessories
• Small production batches
• Replacement components

This can reduce the need for dedicated tooling for every low-volume requirement.

Material Selection

Material selection is particularly important around bioprocessing equipment.

Engineers should consider:

• Temperature
• Humidity
• Chemicals
• Cleaning agents
• Sterilisation requirements
• Mechanical loads
• Fluid exposure
• Surface characteristics

A material appropriate for a dry laboratory fixture may not be suitable for direct contact with a biological process.

For critical applications, material and manufacturing validation should be established before operational deployment.

Designing for Additive Manufacturing

Additive manufacturing allows designers to rethink how small components are constructed.

A printed component may incorporate:

• Integrated mounting features
• Cable channels
• Lightweight structures
• Custom clips
• Modular interfaces
• Part consolidation
• Complex geometry

Designers should still account for layer orientation, dimensional tolerances, wall thickness, fastening methods, and material behaviour.

Sterility and Hygiene Considerations

Bioprocessing environments can have strict cleanliness requirements.

A printed component should not be assumed suitable for sterile or hygienic applications simply because it has the correct dimensions.

Relevant considerations can include:

• Surface finish
• Porosity
• Cleaning procedures
• Sterilisation method
• Material stability
• Contamination risk
• Process compatibility

For critical process-contact applications, specialised manufacturing and validation may be necessary.

Rapid Iteration During Equipment Development

Bioprocessing systems can require frequent design changes during research and development.

A sensor may need repositioning. A tube may require a different routing path. A sample container may change dimensions.

3D printing supports rapid physical iteration.

A typical workflow can be:

CAD design → prototype → fit testing → process evaluation → design revision → new prototype

This approach can help identify practical problems earlier in development.

Digital Spare-Part Management

Companies can maintain digital records of approved printed components.

A digital library can include:

• CAD files
• Part numbers
• Material information
• Equipment compatibility
• Revision history
• Manufacturing instructions

This creates a repeatable method for reproducing suitable low-volume components.
